hello dear fellow

if you want my advice ,, I have both N900 as a primary work phone and N9 as a personal phone and love both of them..

N900 as from my point of view is strong solid one more than N9 even though not enough supported apps

N9 is running smoothly depends how you use it and light comparing to N900

if you are a normal user only caring about FB and Whatsup then go for it cause it is better than yappari in N900

also you tube and watching videos is more fun than N900

Battery consumption in N900 is a bit faster than N9 and am facing this now

if you want more experience and more apps with a reasonable budget.. then go for MOTO G mid range but powerful...
